Create LUNs on Disk Array


To create the LUNs on the Disk Array, the administrator selects the “Provision Storage and Create Volume” scenario from the upper section of the management console. This directs the administrator in the appropriate steps to take.

The right-side panel of the management console is context sensitive, and changes based on the item selected on the left side of the panel. Highlighting “Share and Storage Management” on the left panel console tree brings the “Provision Storage” wizard into view on the right side.



Selecting the “Provision Storage” action on the right side initializes the wizard for this function. The wizard allows the administrator to step through the provisioning process. Notice that the left side of the wizard lists each of the main steps in the process.



The storage subsystem must be selected and in this case there is only one subsystem to select. It is of type “Fibre Channel” because the internal interface to the disk subsystem is listed as Fibre Channel even if SAS is used. This will be changed in the next version.



The LUN type must be chosen from among the various types of LUNs available. In this example, we have chosen a “striped” LUN type. Each type of LUN has a maximum size that depends on the type.





Note – It is important at this point to note that the storage solution LUN size should not be confused with the size of the iSCSI target. The iSCSI target will be configured in a later step and is associated with the storage needed for a particular application on the host server. It is recommended that the LUN size on the storage hardware be as large as reasonably possible to allow the storage subsystem to optimize the use of the physical disks underlying the LUN that is created. In this case, as shown below, we are choosing to create one LUN at the maximum size available for this hardware. The iSCSI targets created later will fit into this one LUN, based on the needs of the host application.

The LUN created will be assigned to this internal storage server only. In a later step, iSCSI targets will be created that will be assigned to external application servers.



The name of this server needs to be provided for the assignment.
